5. sgt soul - 1
6. Tad - 1

DAY 1:

Q: Find two of the three words which can be paired to form an anagram of one word which is a synonym of the word remaining.
EXAMPLE:
LEG - MEEK - NET
LEG + NET = GENTLE
GENTLE is a synonym of MEEK

1. BIDS-SEE-TOO
2. VEERED-WEAK-TAN
3. SIT-HIND-POORER
4. OUT-KISS-SCALE
5. POST-SLAP-AIDE

A: 1. Bids + See = Besides = Too
2. Tan + Veered = Enervated = Weak
3. Sit + Poorer = Posterior = Hind
4. Out + Scale = Osculate = Kiss
5. Slap + Aide = Palisade = Post


DAY 2:

Q:In 10 years time the combined age of two brothers and two sisters will be 100. What will it be in 7 years time?
A: 88


DAY 3:

Q: Find the next number in the series: 199 280 344 360 396
A: 477


DAY 4:

Q:The number 3025 is a rare number that has the ability to be split in half, the two halfs added together and squared, to result in the original number.

Ex:
30+25=55
sqr(55) = 3025

Name the only other 4 digit numbers to do this
(Hint: there is 2)
A: 2025 & 9801



DAY 5:

Q: Which circle goes at the top?

A: C


DAY 6:

Q:
Insert a 3 or 4 letter word (as indicated by the number of *) into the brackets that when added onto the end of the first word and the begining of the second word, form a new word.

ARC (***) RING
ARC (HER) RING
Archer herring


1. TAIL (****) WAY
2. FEED (****) BONE
3. DRY (****) YARD
4. CHAIR (***) KIND

6. BELL (***) FRIEND

A: GATE / BACK / DOCK / MAN / OFF / BOY


DAY 7:

Q: Hostility , Intermezzo, Joyfully, Heifer, Fiddlesticks, Lockjaw

What word will logically come next:

• Publisher
• Racehorse
• Tormentor
• Galantine
• Cantabile
• Whimsical

A:Galantine - Each words starts with the letter whse position in the alphabet coincides with the number of letters in the preceding word. Lockjaw has 7 letters, G is the 7th letter of the alphabet.


DAY 8:

Here is a simpler one :)

Q: A committee of six is to be formed from a group of seven men and four women. How many different committees can be formed if at least two women are always included in each committee?
A: 371


DAY 9:

Q: 100, 90, 84, 74, 63, 53, 43, 33. What number comes next?
A: 22 - Count the letters in the number and subtract that from the original number. OneHundred = 10 letters. 100-10=90


DAY 10:

Q:One man can mow a cricket ground in 2 hours.
Another man can mow a cricket ground in 3 hours.
Another man can mow a cricket ground in 4 hours.
Another man can mow a cricket ground in 5 hours.
Another man can mow a cricket ground in 6 hours.

If they all worked together over the same area at their respective speeds, and assuming they did not obstruct each other, how long would they take collectively to finish the job?
A: 41.4 Minutes


DAY 11:

Q:A days production of batteries has 10% spoilage. If three batteries are selected at random, what are the chances that all three will be defective?

1. BIDS + SEE = BESIDES = TOO

am I doing it right?

Yes

1. Bids + See = Besides = Too
2. Tan + Veered = Enervated = Weak
3. Sit + Poorer = Posterior = Hind
4. Out + Scale = Osculate = Kiss
5. Slap + Aide = Palisade = Post

From: J_Pizzle

Its okay, tomorrows will be a math/logic one.

What time is it where you are? Can you do it in 48 minutes :D ; for it is 23:22 right now.

Its 23:25 for me.

But I am going to bed, I will post in the morning.

Osculate? This is a joke right? That's not a puzzle, that's see who can use an anagram solver the fastest :p

Post some that people can't cheat on if you can please :)

DAY 2:

Q:In 10 years time the combined age of two brothers and two sisters will be 100. What will it be in 7 years time?

88?

It is 88.
:( Nava got it though.

i get 88…

94

ill walk you through it

In 10 years time the combined age of two brothers and two sisters will be 100.

each set is separate two brothers are separate from the sisters

that mean that each person is 50 and 3 year before they were each 47

47 + 47 = 94

^ Each person isn't 50.

47 + 47 = 94

That sounds awfully wrong.

I've come to the same answer as Nava, Sex & Canadaman.
I'll put the reasoning in white text.. if you wish to read it..

In 10 years, the combined age of 2 brothers and 2 sisters will be 100

Now, as it is 4 people, in 10 years they will have aged a total of 40.

Therefore, their combined age right now must be 60.

In seven years, their age will be:

60 + 4*7 = 88.

~RM

4 people all adding up to 100 after 10 years. In 3 years less than 10 years, they have aged how much? 100 - (4 * (10 - 7)) = 88

From: The Claw
4 people all adding up to 100 after 10 years. In 3 years less than 10 years, they have aged how much? 100 - (4 * (10 - 7)) = 88

Thats to simple IMO, I think it trickier then it looks because that jsut the way these things usually are

But.. your solution doesn't make sense.

By the way, I did it the way that RM did.

That's the trick :p The fact it looks tricky when its not.
J_Pizzle's makes sense when you take it as 2 people, not 2 sets of 2 people.

Other problems from the same source don't seem to use tricky wording, so I would take it at face value.

I did it like this.
100/4-3*4=88
100 divided by four because four people.
-3 because 10 years - 3 years equals seven years.
Multiply by four because 4 people.

or

100-(3*4)=88
3*4 because 10-7 is 3 and four people.

^ Since when has 10 - 3 been three? :D

What the hell, O_O!? 10-7=3*

88 Was the right answer (Goes to Nava2)


DAY 3:

Q: Find the next number in the series: 199 280 344 360 396

My guess is 477.

edit: Here's an explanation of how I came to my answer (highlight over if you're interested):

If you take a look at the differences between each number, you'll notice that they're all perfect squares. Taking the square root of these numbers gives you the middle number in each of the three digit numbers in the series. From there, you can deduce that the difference between the last number listed and the next, unknown value in the series will be nine squared, or eighty-one.

404?

477 and 526.

From: aran armath
477 and 526.

Hehe two Answers eh?

477 Was the answer to day 3 (Method got it)

DAY 4:

Q:The number 3025 is a rare number that has the ability to be split in half, the two halfs added together and squared, to result in the original number.

Ex:
30+25=55
sqr(55) = 3025

Name the only other 4 digit numbers to do this
(Hint: there is 2)

2025 and 9801 should be the other two.

I wrote a little program to calculate them:

public class Main {

	public static void main(String[] args) {
		for (int n = 1000; n < 9999; n++) {
			int hi = n / 100;
			int lo = n % 100;
			int sum = hi + lo;
			if (sum * sum == n) {
				System.out.println("Match: " + n);
			}
		}
	}
}

There are like 70 of them.

There are 72 to be exactc, i counted them tonightt.

the question calls for a 4 digit number.

The answers are 2025 & 9801 (Method)

And there are only 2 answers (not 5, not 70, not 72. Only 2)

DAY 5:

Q: Which circle goes at the top?

E..

I see a pattern, not sure if right. C.

actually I think it's C, good job Pickle tickler :p, my first post was a guess :p
now that I look, I go with C.

C.. they beat me lol

C.

You "add up" the two images, and "erase" the overlapping lines.

~RM

Answer was C (mrpickle)

DAY 6:

Q:
Insert a 3 or 4 letter word (as indicated by the number of *) into the brackets that when added onto the end of the first word and the begining of the second word, form a new word.

ARC (***) RING

1. gate
2. back
3. dock ?
4. man
5. off
6. boy

I'm not sure about number three. It seems like 'back' would work also.

1. gate
2. back
3. land?
4. man
5. off
6. boy

Number 3 might be wrong. That's not how you spell lanyard, but maybe there isn't restrictions on that or I'm smarter than the test? :p

Haha weird, did it at the same time..

1. gate
2. back
3. ly
4. man
5. off
6. boy

^ 3 isn't right.. :p

GATE / BACK / DOCK / MAN / OFF / BOY (Method)


DAY 7:

Q: Hostility , Intermezzo, Joyfully, Heifer, Fiddlesticks, Lockjaw

What word will logically come next:

• Publisher
• Racehorse
• Tormentor
• Galantine
• Cantabile
• Whimsical

My guess is Cantabile, but I couldn't really tell you why I chose that one.

Tormentor. I found one working pattern and that is what came out.

Whimsical

Galantine, because nobody else chose it :)
I am really struggling with these, I saw some of the previous questions and it makes me feel not very smart :p

Publisher!

I'm gonna say: Height

Racehorse!

Galantine - Each words starts with the letter whse position in the alphabet coincides with the number of letters in the preceding word. Lockjaw has 7 letters, G is the 7th letter of the alphabet.

DAY 8:

Here is a simpler one :)

Q: A committee of six is to be formed from a group of seven men and four women. How many different committees can be formed if at least two women are always included in each committee?

A: 9

If 'sic' is supposed to be six, my answer is 371.

217? <- wrong…

315

Edit: I plugged in a wrong number, Method is right.

I swear I had like this exact question in math 30. Doesn't it have to do with factorials or the nPc shit?

From: Blumblebee
I swear I had like this exact question in math 30. Doesn't it have to do with factorials or the nPc shit?

Yes, I'm pretty sure it does have to do with combinations and permutations, though you'll have to decide which one to use.

442

A: 371 (Method)


DAY 9:

Q: 100, 90, 84, 74, 63, 53, 43, 33. What number comes next?

21?

20 or 26 ( my math says i can be ether one >.>)

I'm not really sure on the pattern here, but my guess is 9.

I'm going with 23

A: 22 - Count the letters in the number and subtract that from the original number. OneHundred = 10 letters. 100-10=90
(No one got the answer)
(AHHHHH Dgby714 you shouldn't have deleted you're answer, even though it was a guess, it was correct :p)


DAY 10:

Q:One man can mow a cricket ground in 2 hours.
Another man can mow a cricket ground in 3 hours.
Another man can mow a cricket ground in 4 hours.
Another man can mow a cricket ground in 5 hours.
Another man can mow a cricket ground in 6 hours.

If they all worked together over the same area at their respective speeds, and assuming they did not obstruct each other, how long would they take collectively to finish the job?

41 and 11/1200 minutes (~41.379) or 20/29 (~.670) hours.

Ugh, I also had 22 before changing my answer for the last one

0.690h or 41.679mins

I also got 20/29 of an hour. ~41.37931 minutes, ~.689655 hours.

Dang, I'm late. 0.69 hours.

Indeed, 20/29 hours is what I got also, but I'm a few hours too late.

4 hours… hmm i guess my guess was right on the last one lol to bad i deleted it

I guess I'm late too? how fun. Great.

My answer: 41 minutes 22 seconds 758 milliseconds

36 minutes 87%
36/87 = .413793
.413793*100=41.3793

41.4 Minutes (Tad)


DAY 11:

Q:A days production of batteries has 10% spoilage. If three batteries are selected at random, what are the chances that all three will be defective?

.1% or 1/1000 ?

1/100000?

:3 I'm probably way off.

I got what Ogre got first but then I was like "No wait if it's a percent you times it by 100 or something" so I did.

DAY 11:

Q:A days production of batteries has 10% spoilage. If three batteries are selected at random, what are the chances that all three will be defective?

Doesn't it depend on the amount of batteries produced?

If you have 10 batteries, there is no chance that 3 will be defective, but if you have 100 batteries, there is X chance. And so on.

^ lolwut? That's not possible.

0 <= chance <= 1

And in this case, it's not equal to 0 or 1.

0.001%

?

From: i luffs yeww
^ lolwut? That's not possible.

0 <= chance <= 1

And in this case, it's not equal to 0 or 1.

No, in order to find the percentage (0-1):

There is either spoiled or not spoiled. This is a binomial distribution (Either success or failure). The chance (P(X=r)) is equal to C(N over R)p^r(1-p)^n-r

Where X is equal to the amount of successes.

So in this, the success can be considered to be a battery failing, which is 0.1

But for it to work, you need N, which is the number of trials.

Without it, you wont find the answer, says my equation. Perhaps I overthought it.

E: Potential answer is 0.001 = 0.1%

I think ian got it before I wrapped my head around it.

My guess is 2/2695, or about a 0.0007 chance.

^ uhh wat

Hobbit said that Ogre or I was right on irc. I think.

From: i luffs yeww
^ uhh wat

Hobbit said that Ogre or I was right on irc. I think.

Yay I had the same answer :)

From: i luffs yeww
^ uhh wat

Hobbit said that Ogre or I was right on irc. I think.

If he did, then nevermind. I think I figured you would be taking one battery at a time (out of 100, let's say), so the chance of finding a defective battery would decrease if you picked one each time (10/100, then 9/99, then 8/98). I used those numbers to calculate my probability.

Method, that was my second thought, but that's wrong, they explained it to me.

3% im guessing again =P Did the math and Orge got it …. wish i remembered how to do it quicker >.>

^ chance * chance * chance? :p

1/10 * 1/10 * 1/10.
